1 Brief Explanation
1.1 Tool management functions
Tool management involves support of the machining process by providing the tool specified in
the part program and the tool data relevant for the tool change, and by partially controlling the
tool change.
Another function of the tool management software is the input and output of tool data available
on tape, code carrier or the host computer to and from the SINUMERIK system via the
interface generated by the software package (data output via tape only possible from version
3.0 onwards). The data handling for the data input and output is partly suited to the specific
features of the machine configuration and the strategies chosen for loading and unloading.
Generally, the tool management software is subdivided into the areas "data maintenance" and
"program and/or functions". The program/function area processes the memory areas provided
by the data maintenance, supports control of the machine and keeps a record of and updates
the required image of the magazine and buffer assignment in accordance with the tool flow at
the machine.
The following list shows the various functions, together with possibilities and aids, offered by
package 1 for different applications:
• Tool selection for cartridge, chain and rotary-plate magazines and turrets for active tools
and replacement tools:
– Tool change
– Workpiece and tool measurement
– Loading point
• Search for empty location and run spindle without a tool if T=0
• Selection of sense of rotation for chain and rotary-plate magazines and turrets
• Initiation of the tool change in the tool-changing cycle after positioning the magazine/turret
and/or the spindle.
• Data handling necessitated by the tool flow:
– During the tool change;
– During the loading and unloading procedures;
– During sorts of tools that might be necessary within a magazine and/or in several
magazines.
• Flexible or fixed/old location coding can be defined individually for every tool.
• Generating the required magazine tables and turret tables in data blocks of the PLC in
accordance with the PLC machine data entered.
• Examples of operator interfaces and their reference to the functions/functionality of the tool
management on the basis of assumed machine configurations.
• Examples - irrespective of the operator interface examples - which show possible
applications of tool management.
Parameter assignment of the FB package has to be carried out by the user, because he can
take account of the machine configuration. It is also up to the user to link the machine program
with the user interfaces of the FB package.
